Access loses more data than SmartHub

I have a SmartHub and an Access.  They share 2 thermometers.

Over the last 11 days for the SmartHub, I see 97% and 98% captured measurements.  For the Access, I see 94% and 92% captured measurements.

The 2 hubs sit right beside each other.

They should not be  "right beside each other"... along with your router everything needs to be separated as much as possible to prevent interference, if you can't achieve this purchase longer Ethernet cables.

That makes no sense,  I tried it with a 50ft cable and right next to the old hub had the same issues.

They were both right by the router. I've moved them 3-4 ft in opposite directions. I'll collect stats again in a week or so.

It makes every bit of sense there can be RF interference, you have other issues going then. Try a different Ethernet cord?, is your power supply output 4.5vdc? I had one only supplying 1-2v.

It's something to try anyway.

Do we know that the hubs actually transmit? If they only receive, why would interference with each other be an issue?

Duane,

SmartHUB's and Access do not intentionally transmit. They do have a microcontroller and Ethernet transceiver inside that is capable of unintended radiation. I believe these devices temporarily blank off their own receivers when blasting out Ethernet packets, so as to not self-interfere. Dan is correct, though. Hub or Access devices should be kept away from one another, just as with any other electronic device, and especially WiFi routers.

Where do you see the measurement loss stats? Which page?

There is no page for that that I know of.  I download the measurements and look at them with my own programs. They're reported every 5 minutes so missing ones stand out.

Thanks, I’ll try that.
